Photoshop moving a layer

Howdy folks does anyone know how to shift a layer in Photoshop CS3? Im basically looking to replicate the same thing as selecting the layer and hitting the arrow keys x amount of times. The dictionary shows a move command, but I can’t figure out the syntax.

Any ideas that don’t involve sending key clicks?

translate layer 1 delta x 100
translate layer 1 delta y 100

I always work in pixels
